The Reference Desk/River's Binary heart System

I have a question about the Binary Heart System. In one story, there is a mention that River Song has a Binary Heart system because of her DNA being manipulated, on Demon's Run, by Madam Kovarian. So on the BH System page, there is no mention of River Song having 2 hearts. Can you confirm she has indeed 2 hearts, or is the info wrong? Here is River song's page: Link titlehttp://tardis.wikia.com/wiki/River_Song
